BM automatic calculation method for plant stationary equipment

A BM (Bill of Material) automatic calculation method of plant stationary equipment implemented by a computer, comprising the steps of:

• (a) performing strength calculation for each item of a stationary machine having each unique number based on process data required in a plant using a strength calculation program and extracting input data in a first format from a strength calculation result for each item in which the strength calculation is performed;
• (b) extracting all object data for each item, including nozzle data, design data, material specification data, and detail drawing data for preparing drawings from the extracted input data in the first format and converting all of the extracted object data into a second format;
• (c) extracting only information on a part where an item-specific plate is used from all of the object data for each item converted into the second format and generating total part list data interlocking with an MPS (material purchaser specification) number sheet in information data for an extracted part where the item-specific plate is used;
• (d) loading the total part list data as input data in a BM calculation program;
• (e) setting a standard of a purchasing plate built with a library within the BM calculation program;
• (f) setting cutting and fabrication margins for each part for preparing cutting plan drawings built with the library within the BM calculation program;
• and
• (g-1) preparing a cutting plan drawing according to the set cutting and fabrication margins for each part;
• (g-2) preparing a nesting plan drawing optimized by disposing the cutting plan drawing in the standard of the set purchasing plate;
• and
• (g-3) generating a BM (bill of material) list and a cutting plan part list data that matches a BM number listed in the BM list, based on the nesting plan drawing.
